What are the factors that enable the President of France to constrain the Prime Minister of France

The Constitution of the Fifth Republic of France provides for a system of government dominated by the prime minister, but the Constitution also provides the possibility for the president to arrogate to himself the power of the prime minister. In the actual political operation process, between the president and the prime minister has been showing a "strong" president and "weak" prime minister power imbalance. One important reason for this imbalance is that the French president not only holds his own political power resources, but also controls the administrative power resources belonging to the prime minister.
